There is PostDominatorTree for determining post-dominance. Even if A post-dominates B and B is executed, that doesn't guarantee that A will be executed. For example, there could be an infinite loop in-between. Strong post-dominance makes the stronger guarantee that there will be no infinite loop from B to A. Do we have anything in LLVM for determining strong post-dominance and in general for

It is possible to see the print queue and via NT4's printer window. Correct? And remove the jobs too, right? But not for me. cups-1.0.5, samba-2.07 on linux-2.2.15 queues show ok using lpq printing from nt works ok using samba. in smb.conf I have: printing = cups print command = lpr -P%p -s %s; rm %s lpq command = /usr/local/bin/lpq -P %p lprm command = /usr/local/bin/lprm -P %p %j The

I have a problem with samba 2.05a on my irix-6.5 box. Now I know this must be a user problem because I have run samba on this machine before. Samba compiles and runs fine and I have tried the precompiled version too. I have /tmp shared out as [tmp] and get the following messages in log.smb when I try to connect to it using smbclient from the localhost smbd version 2.0.5a started. Copyright

*** Summary I'd like to propose (and implement) functionality in LLVM to determine when a poison value from an instruction is guaranteed to produce undefined behavior. I want to use that to improve handling of nsw, inbounds etc. flags in scalar evolution and LSR. I imagine that there would be other uses for it. I'd like feedback on this idea before I proceed with it. *** Details Poison

Im running 2.0.6 on solaris 7 on an ultra sparc and have discovered the following strange behavior: Samba was configured with --prefix=/usr/local/daemon/samba with this directory being a link. /usr/local/daemon/samba -> /localhost/daemon/samba-2.0.6 smbd and nmbd are looking for smb.conf in /usr/local/daemon/samba/lib and this is where the file is. Changes to smb.conf are noticed and acted

Im using samba 2.07 from source on a digital unix 4.0e machine. Users are connecting to their unix home directories fine. There are also samba print shares. Im using cups-1.0.5 for the print server but this problem looks like it's part of samba. The authenication is done from a NT server. Ie the global section of smb.conf [global] workgroup = ee-student debuglevel = 3 server string

Hi Sanjoy, thanks for your thoughts on this.

There's also bug 23527 for GEP. Sounds like there might be more such bugs. One
